Description
Technical field
The utility model relates to five metals pipe fitting, particularly relates to a kind of telescopic pipe used for mop, clothing fork, glass scraper etc. above.
Background technique
In the modern life, limited because of living space, people more and more see the collection volume of heavy articles (particularly daily necessities), wishing that they are collapsible when not using, can zoom in volume, so that collection.Therefore, the various structure point reducing article volume is come out of steamer, and the common flexible pipe structure as the use of stock handle is one of them, and this structure is made up of interior pipe, outer tube and fastening-connecting device thereof, and when not using, internal tube shrinks enters in outer tube, and size is short.Stretch out certain length in interior Guan Kecong outer tube during use, and locate fastening good, increase to make size.In flexible pipe structure, the location after the connection of inner and outer pipe and interior pipe stretch out is fastening is all rely on fastening-connecting device to realize, and therefore, fastening-connecting device is the critical component in flexible pipe structure.
Existing connection set is general all by the mode of structure of two-part by screwed tight, needs very great strength just can tighten, and there will be the wearing and tearing between screw thread after Long-Time Service, cause and tighten inefficacy, cause and cannot use when tightening.
Model utility content
In order to solve the problems of the technologies described above, the utility model devises a kind of telescopic pipe, tightens inconvenience and the problem of Long-Time Service inefficacy to solve existing telescopic pipe.
The technical solution of the utility model is: this telescopic pipe comprises pipe, lower pipe and locking device, top tube and down tube are hollow structure, lower pipe box is connected in pipe, locking device is arranged at position, top tube and down tube joint, locking device comprises upper cover, overcoat, inner sleeve and brake pad, inner sleeve is placed on jacket internal, overcoat can rotate relative to inner sleeve, inside put and be provided with mounting hole, brake pad is located in mounting hole, be provided with two positioning convex in outer sleeve, the outer sleeve wall thickness between two positioning convex is respectively in reducing gradually clockwise.
As preferably, described brake pad and lower pipe joint place are provided with encapsulate.
As preferably, described upper pipe upper end is provided with hand handle, and hand is being provided with hand outward encapsulate.
As preferably, described lower pipe upper end is provided with silently.
As preferably, described lower pipe lower end is provided with joint, and joint is fixed by blind rivet and lower pipe.
As preferably, described upper cover and overcoat are threaded connection.
As preferably, the quantity of described brake pad is at least two pieces.
The beneficial effects of the utility model are: flexible rod of the present utility model, by devising novel fastening-connecting device, decrease the difficulty locking and tighten, easy to use; Simultaneously by being provided with a removable brake pad, when after use wearing and tearing, conveniently replaced, improve working life.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in figs. 1-7: telescopic pipe of the present utility model comprises pipe 2, lower pipe 4 and locking device 3, upper pipe 2 and lower pipe 4 are hollow structure, lower pipe 4 is socketed in pipe 2, lower pipe 4 upper end is provided with silently 7, locking device 3 is arranged at pipe 2 and position, lower pipe 4 joint, locking device 3 comprises upper cover 10, overcoat 11, inner sleeve 12 and brake pad 13, upper cover 10 and overcoat 11 are threaded connection, it is inner that inner sleeve 12 is placed on overcoat 11, overcoat 11 can rotate relative to inner sleeve 12, inner sleeve 12 is provided with mounting hole 15, brake pad 13 is located in mounting hole 15, overcoat 11 is provided with two positioning convex 16 in managing, overcoat 11 thickness of pipe wall between two positioning convex 16 is respectively in reducing gradually clockwise.
The quantity of brake pad 13 is at least two pieces, ensures its enough coupling mechanism force.
Brake pad 13 and lower pipe 4 joint place are provided with encapsulate 14, and encapsulate 14 can increase the friction with lower pipe 4, more stable after making locking.
Be provided with hand 1 in upper pipe 2 upper end, hand being provided with hand outside 1 encapsulate 6, hand encapsulate 6 for holding time more comfortable, also increase frictional force simultaneously and prevent landing when being affectedly bashful.
Lower pipe 4 lower end is provided with joint 5, and joint 5 is fixed by blind rivet 8 and lower pipe 4, and joint 5 lower end is provided with fixture block, can fix mophead, scrapes brush, clothing fork etc.
The utility model in use, when needs are locked, according to B direction rotary sleeve 11 in Fig. 5, when inwall due to overcoat 11 rotates along B direction, wall thickness increases relatively gradually, and overcoat 11 inwall touches brake pad and extrusion friction block 13 inwardly close lower pipe 4 gradually, when the positioning convex 16 on overcoat 11 inwall withstands inner sleeve 12, when brake pad 13 contacts with lower pipe 4, frictional force arrives maximum, now namely completes lock operation.
When needs stretch, according to C direction rotary sleeve 11 in Fig. 6, when overcoat 11 reverses, reduce the extruding to brake pad 13 gradually, and then brake pad 13 not pipe 4 under a touch, lock pulls lower pipe 4 after opening under thinking, just extending.
The above is only preferred implementation of the present utility model, for those skilled in the art, under the prerequisite not departing from the utility model principle, can also make some improvement, and these improvement also should be considered as protection domain of the present utility model.
